Re: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction
Rats, the thread broke, hence my other reply. Like everyone says, you
need to check the return value of getRemoteUser() - try looking at the
value of the hidden field in the HTML via IE's 'Show page source'.

It is impossible for request.getRemoteUser(); in my
JSP returning a null. (see code below) Before it
reaches request.getRemoteUser(); the user has already
been successfully logged in with a valid name.

Are you having problems with the username or the

it is the username, then I'd suspect that

Subject: Re: Please Help! Unable to Pass A Hidden
Field To
scaffold.ProcessAction
I did not mess up lowercase and uppercase of the
hidden field I want to pass from my JSP to the
scaffold.ProcessAction. If
it had been the lowercase/uppercase problem, I would
have gotten a message
saying that the variable could not be recognized.
I pass two hidden fields at the same time. One of
them is successfully passed with correct value. The
other is passed but its value shows a 'null' in the
scaffold.ProcessAction.
What could go wrong? Let me show my code again:
Two hidden fields: username and keyName are passed
from a JSP via a SUBMIT button:
req:isUserInRole role=editor
html:form action=/find/Category
% String username = request.getRemoteUser();%
html:hidden property=keyName
value=journal_category/
html:hidden property=username
value=%=username%/
html:submitView Articles/html:submit
/html:form
/req:isUserInRole
and an action mapping:
action
roles=editor
path=/find/Category
type=org.apache.struts.scaffold.ProcessAction
parameter=org.apache.artimus.article.FindEditorData
name=articleForm
scope=request
validate=false
forward
name=success
path=.article.Result/
/action
The value of the 'username' is found to be a 'null'
in
the FindEditorData.java while the value of keyName
is successfully
retrieved. In the browser, I got:
name=null; kn=journal_category; kv=null
The code of my FindEditorData is shown below:
public final class FindEditorData extends Bean
{
public Object execute() throws Exception
{
// Obtain username
String username = getUsername();
EditorService service = new EditorService();
String value = service.findEditorData( username
);
String property = getKeyName();
if (( null==property ) || ( null==value ))
{
StringBuffer sb = new StringBuffer();
sb.append( name= );
sb.append( username );
sb.append( ; kn= );
sb.append( property );
sb.append( ; kv= );
sb.append( value );
throw new ParameterException(
sb.toString() );
}

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction
I followed your advice. In the Bean.java, I did the
following:
private String username = natalie;
public String getUsername() {
return this.username;
}
public void setUsername(String username) {
this.username = username;
}
and I compiled all the relevant classes, re-run the
application, the FindEditorData.java writes out the
following in the browser:
The process did not complete. Details should follow.
name=natalie; kn=journal_category; kv=null
Now, the question is why the Bean.java does not pick
up the value of the hidden field 'username' from my
JSP while successfully picks up the value of the other
hidden field 'keyName'.
There is some data processing activities going on in
the FindEditorData.java:
String username = getUsername();
EditorService service = new EditorService();
String value = service.findEditorData( username );
The above data accessing codes had been tested outside
the environment of the application (the codes did what
I expected them to do without problem) before they
were integrated into the application.

I did another test. I took out those data access
activities in the FindEditorData.java and ran the

of data access activities have nothing to do with the
value of the 'username' becoming null in the

Caroline,
In your FindEditorData.java class, is the value
for
your username variable null or null? If it is
null,
then you are reading the wrong request parameter
since
request.getParameter() will return null if the
parameter doesn't exist. If the String value is
null, then you have a problem with
getRemoteUser()
Why don't you dump request parameters that you
are
getting in your FindEditorData?
Hidden input tags work fine.

Hi, I think that we are in different time

As you have mentioned, I, too, suspected that
the
statement in my JSP:
request.getRemoteUser();
returns nothing. Therefore, I did a test in
my
JSP.
In addition to request.getRemoteUser(); I
created
another String manually:
req:isUserInRole role=editor
%
String username = request.getRemoteUser();
String userrole = author;
%
% out.println(The user name is: + username
+.);
%
% out.println(The role is: + userrole
+.);
%
/req:isUserInRole
And the browser shows:
The user name is: Gloria Jen. The role is:
author.
Gloria Jen is the name that I provided while
logging
on and authenticated by the container.
Therefore,
the
request.getRemoteUser(); does not return a
null.
And
I hope that it means I am not passing a null
value
when I use the hidden field technique.
Then, I pass two hidden fields (with value in
them)
from my JSP to a Java class
(FindEditorData.java),
which is of scaffold.ProcessAction type. One
of
the
field is passed with its value correctly
retrieved.
The other field is passed with its value found
to
be
null.
What could go wrong? I have been thinking
about
it
for days and so do those who try to help me.

getRemoteUser
public java.lang.String getRemoteUser()
Returns the login of the user making this request, if the user has been

Returns: a String specifying the login of the user making this request, or
null
As the JavaDoc says: Whether the user name is sent with each subsequent
request depends on the browser and type of authentication. Are you using
basic authentication or are you authenticating the user yourself?
If you are doing it yourself (ie. through a db lookup) then the server
doesn't know about the user being authenticated and will return null.

scaffold.ProcessAction. If it had been the lowercase/uppercase problem,
I would have gotten a message saying that the variable could not be
recognized. I pass two hidden fields at the same time. One of them
is successfully passed with correct value. The other is passed but its
value shows a 'null' in the scaffold.ProcessAction. What could go
wrong? Let me show my code again: Two hidden fields: username and
keyName are passed from a JSP via a SUBMIT button: % String
username = request.getRemoteUser();% value=journal_category/
value=%=username%/ View Articles and an action mapping:
roles=editor path=/find/Category
type=org.apache.struts.scaffold.ProcessAction
parameter=org.apache.artimus.article.FindEditorData
name=articleForm scope=request validate=false
name=success path=.article.Result/The value of the
'username' is found to be a 'null' in the FindEditorData.java while
the value of keyName is successfully retrieved. In the browser, I
got: name=null; kn=journal_category; kv=null The code of my
FindEditorData is shown below: public final class FindEditorData
extends Bean { public Object execute() throws Exception { //
Obtain username String username = getUsername(); EditorService
service = new EditorService(); String value = service.findEditorData(
username ); String property = getKeyName(); if (( null==property
) || ( null==value )) { StringBuffer sb = new StringBuffer();
sb.append( name= ); sb.append( username ); sb.append( ; kn= );
sb.append( property ); sb.append( ; kv= ); sb.append( value );
throw new ParameterException( sb.toString() ); } ResultList list =
new ResultListBase ( Access.findByProperty( this,property,value

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction
I must pass the result of request.getRemoteUser()
because it is a Java class that receives the
hidden field. If you read my code carefully, you will
see that FindEditorData.java is a Java class and I
cannot use 'request' or 'session' in a Java class. It
takes a servlet or a class extends Action to use
'request' or 'session'.
But, this class is of ProcessAction type defined in
the struts-config.xml:
action
roles=editor
path=/find/Category
type=org.apache.struts.scaffold.ProcessAction
parameter=org.apache.artimus.article.FindEditorData
name=articleForm
scope=request
validate=false
forward
name=success
path=.article.Result/
/action
And, it is easy to see that I use container-managed
authentication. In my JSP, there is req:isUserInRole
role=editor before reaching % String
username=request.getRemoteUser(); % Again, I have
provided my code:
req:isUserInRole role=editor
html:form action=/find/Category
% String username = request.getRemoteUser(); %
html:hidden property=keyName
value=journal_category/
html:hidden property=username
value=%=username%/
html:submitView Articles/html:submit
/html:form
/req:isUserInRole

Caroline,
Why are you passing the result of
request.getRemoteUser() in a hidden
variable anyway since it is available as part of the
HttpRequest and thus
will be available in the action class?

It is impossible for request.getRemoteUser(); in my
JSP returning a null. (see code below) Before it
reaches request.getRemoteUser(); the user has
already
been successfully logged in with a valid name.
req:isUserInRole role=editor
% String username = request.getRemoteUser();%

Caroline,
What is the return value of getRemoteUser() ?
